Update from this weekend, spent some time Saturday buttoning up the rear sub-frame. I never took any pics but the gas tanks are back up. After bolting on my garagtastic poly subframe mounts and lifting the sub-frame back up into place I noticed that the diff hanger was too long. That's because the flange on the garagtastic mounts is welded in the middle of the bushing whereas the factory flange is offset, this caused the sub-frame to be raised about 3/4". So I sliced the hanger in half... trimmed some out and tacked it to test fit...

Fitment was good, so I welded it up, painted and installed...

After that the axles went back on along with the BC coils...

Man those rear axle nuts are crazy... 295-347ft-lb torque spec! My torque wrench only goes to 150ft/lbs... just went by feel after that with a bigger breaker bar until the castle nut lined up with a pin hole.

It's been a while... because I bought a house and am knee deep in renovations... progress will be slow for the next few months...

Recently on thanksgiving weekend, I gave thanks for the EFI M10 motor that I picked up for free a while back, because the one that I had bought before that one must have sat unused with no oil in it for a long time and had too much rust in the bores to use as-is.

So I swapped engines on the stand and started basic tear down to inspect condition and clean things up...

It looks like someone must have had this motor out for a refresh at some point because the block has good coat of black paint on it and some newer yellow zinc bolts on some brackets. I tried picking at the paint and it's on there good, not just a quick and dirty job over the old flaky rust that tends to accumulate on these old blocks.

The valvetrain was also really clean, leading me to believe that the head had been off recently... hopefully not for any terrible reasons...

The only thing I found so far was that the head has a hairline crack on one of the spark plug holes that had been sealed up.

Since it's not structural and there is no evidence on the outside of the head or block that it had been leaking recently, I'm just going to leave it for now. My goal right now is to get the engine in the car and start working on the wiring harness for megasquirt. I have a spare head on the motor I'm not using that I'll clean up and have ready to go in the event that this one starts leaking.

Had a few hours to spare this weekend so I continued working on cleaning up the motor.
I'm pretty well done that task now. Next I'll have to give a few things a coat of paint, then I can re-seal it and drop it into the car so I can start working on the wiring harness.

Over the Christmas holidays I had some time to crack open the MS3 that I bought 2nd hand. I installed the MS3X board and using a couple of gator clips with a 12V DC power supply and a piece of scrap wire I was able to power up the unit and load firmware to it. It should be good to go now when I need it...

Today I took the hood off and got the engine dropped in temporarily...

Now to find some time to start working on laying out the wiring harness!

Took the engine harness off the original motor and labelled everything...

After carefully cutting off the casing, I used the ETM and traced all the wires from the relays to the engine connectors and cut out everything that I wouldn't be needing to run megasquirt. The pile on the right is what I'm keeping...

After that I pulled all the wiring out of the sheathing on the universal harnesses for the MS3 and MS3X, separated all of the wires I need and the ones I don't. Then combined the ones I need and stuff them back into a single sheathing. The pile on the left is all the wiring I don't need...

Pulled it though the firewall and then peeled it back out of the sheathing...

And then set about roughly running the wires to where they need to be and trying to keep everything tidy....

After that I prepped the injector pig tails that I cut off the E30 M10 harness, the old sheathing was hard and cracked so I pulled it off along with the rubber boots, put some new heat shrink and reinstalled the boots

That's about it for now, I'm planning on making the injector harness modular along with some other wiring possibly so I ordered an automotive connector kit that should be arriving this week.
